Infrared photometric and spectroscopic observations of IC~1848 from
two of the instruments aboard COBE are used to derive physical
properties of the dust and gas in the diffuse H II region and in the
molecular clouds heated by the cluster of O stars. With its
$42^{\prime}
\, \times \, 42^{\prime}$ instantaneous field of view,
the Diffuse Infrared Background Experiment (DIRBE) provides 9
independent spectral energy distributions from various parts of the
region covering the spectral range from 1.25 to 240 $\mu$m in 10
bands. Maps of the dust temperature and column density derived from
the DIRBE far infrared observations are presented. A spectrum from
the Far Infrared Absolute Spectrophotometer (FIRAS) shows strong [C~II]
and weak [N~II] line emission.
